Empty parameters passed while using POST in android for raw json data

I am making a new android application and i am a beginner. starting with my Login Activity, i am trying to use POST for sending parameters. but when i debug i found no parameters being passed. Tried almost many answers in stack overflow, none solved my issue. Can anyone help
private void jsonRequestLogin() {
try {
RequestQueue requestQueue = Volley.newRequestQueue(this);
String URL = Constants.LOGIN_URL;
JSONObject jsonBody = new JSONObject();
jsonBody.put("Username", uName.getText().toString().trim());
jsonBody.put("Password", paswd.getText().toString().trim());
final String requestBody = jsonBody.toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("VOLLEY", response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("VOLLEY", error.toString());
}
}) {
#Override
public String getBodyContentType() {
return "application/json; charset=utf-8";
}
#Override
public byte[] getBody() throws AuthFailureError {
try {
return requestBody == null ? null : requestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", requestBody, "utf-8");
return null;
}
}
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String responseString = "";
if (response != null) {
responseString = String.valueOf(response.statusCode);
// can get more details such as response.headers
}
return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
}
};
requestQueue.add(stringRequest);
} catch (JSONException e) {
e.printStackTrace();
}
}

Use getParams() method for requesting the parameters
private void check() {
StringRequest stringRequest = new StringRequest(Request.Method.POST,url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//Log.d(TAG, "onResponse:" + response);
try {
JSONArray responseArray = new JSONArray(response);
JSONObject jsonObject = responseArray.getJSONObject(0);
//Log.d(TAG, "onResponse: jsonArray " + responseArray);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
//Log.d(TAG, "onErrorResponse: " + error);
Toast.makeText(SplashScreenActivity.this, "Some error occurred try after sometimes", Toast.LENGTH_SHORT).show();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> params = new HashMap<String, String>();
params.put("param1",param1);
params.put("param2", param2;
//Log.d(TAG, "getParams: " + params);
return params;
}
};
addToRequestQueue(stringRequest, "");
}

Try to override the headers method and put content type init.
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}

I think you should use retrofit
Retrofit
Retrofit 2

How do i send body data with a JsonObjectRequest? Android-Volley library

I am trying to send data to my server. I create a JsonObject and I pass it as a parameter when creating the JsonObjectRequest. It doesn't give any error, but it is not returning anything. Tried with postman and it is working fine.
This is my code:
JSONObject jsonBody = new JSONObject();
try {
jsonBody.put("firstname", "asd");
jsonBody.put("lastname", "asd");
jsonBody.put("id", "1");
} catch (JSONException e) {
e.printStackTrace();
}
//creating a JsonObjectRequest
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, showPlayersUrl,
jsonBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
JSONArray players;
try{
players = response.getJSONArray("Players");
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
requestQueue.add(jsonObjectRequest);
}

Ok, found the problem. Server side i wasn't accepting the data as json format. Just had to add this and it works:
$_POST = json_decode(file_get_contents('php://input'), true);

Try it:
RequestQueue queue = Volley.newRequestQueue(this);
private void makeJsonObjReq() {
showProgressDialog();
Map<String, String> postParam= new HashMap<String, String>();
postParam.put("un", "xyz#gmail.com");
postParam.put("p", "somepasswordhere");
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
Const.URL_LOGIN, new JSONObject(postParam),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
msgResponse.setText(response.toString());
hideProgressDialog();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hideProgressDialog();
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
};
jsonObjReq.setTag(TAG);
queue.add(jsonObjReq);
}

Send token header in json object paramater Volley post

I am using post method in volley. I searched and found that getHeader() is used to send header in request.The solution was to use JSONObject request instead of string request(which i am using currently) but is there a way of sending header through this method? Because in that case I will have to modify a lot of code in many classes. Sorry for the English, I am not a native speaker.
The request parameter is a json object. I am sending the parameters using following code.
mRequestQueue = Volley.newRequestQueue(getContext());
mStringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("Response", "onResponse: " + response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.i("This is the error", "Error :" + error.toString());
}
})
{
#Override
public String getBodyContentType() {
return "application/json";
}
#Override
public byte[] getBody() throws AuthFailureError {
HashMap<String, String> params2 = new HashMap<String, String>();
params2.put("AssigneeId",userid);
params2.put("IssueStatus", "5");
return new JSONObject(params2).toString().getBytes();
}
};
mRequestQueue.add(mStringRequest);

This request also has StringRequest. Please use the getHeaders() in this way:
public void requestWithSomeHttpHeaders() {
RequestQueue queue = Volley.newRequestQueue(this);
String url = "http://www.somewebsite.com";
StringRequest getRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
// response
Log.d("Response", response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub
Log.d("ERROR","error => "+error.toString());
}
}
) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("User-Agent", "Nintendo Gameboy");
params.put("Accept-Language", "fr");
return params;
}
};
queue.add(getRequest);
}
For JsonObjectRequest:
JsonObjectRequest req = new JsonObjectRequest(Request.Method.GET,url,
null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(tag, response.toString());
activity.hideDialog();
try {
activity.onRequestServed(response, code);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(tag, "Error: " + error.getMessage());
Log.e(tag, "Site Info Error: " + error.getMessage());
Toast.makeText(activity.getApplicationContext(),
error.getMessage(), Toast.LENGTH_SHORT).show();
activity.hideDialog();
try {
activity.onRequestServed(null,code);
} catch (JSONException e) {
e.printStackTrace();
}
}
}) {
/**
* Passing some request headers
*/
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
//headers.put("Content-Type", "application/json");
headers.put("key", "Value");
return headers;
}
};

Android Send POST of JSON raw body with volley

I have to send a post with voley but when i try to send raw body as requested, instead of a response a get this error
******com.android.volley.ServerError******: {"message":"No user account data for registration received."}
i tried the same in postman and it works perfect, how can i fix it in my code?
raw body that works in postman ->
{
"camp1": {
"value": "value"
},
"camp2": {
"value": "value2"
}
}
this is what it is in my code ->
public void requestRegistrationInfo(#NonNull final String camp1, #NonNull final String camp2,final Listener listener) {
RequestQueue requestQueue = Volley.newRequestQueue(context);
requestQueue.add(new JsonObjectRequest(
Request.Method.POST, URL,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.v("IT WORK");
listener.onSuccess();
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("******" + error.toString() + "******", getErrorMessage(error));
listener.onFailure();
}
})
{
#Override
protected Map<String,String> getParams() {
Map<String, String> map = new HashMap<>();
map.put("{camp1", "value");
map.put("camp2", "value");
return map;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> map = new HashMap<>();
map.put("header1", "header1");
map.put("header2", "header2");
return map;
}
});
}
what can i do to send raw json correctly and don't show the error?

In normal case JSONObject request didn't hit the getParams() method , this method only for String request and passing key value pair data payload. If you want to pass a raw body with JSON data , first you have to format your data as server accepted.
In your case this is your data
{
"camp1":{
"value":"value1"
},
"camp2":{
"value2":"value2"
}
}
You have to convert your data to Server accepted JSON format like this
JSONObject jsonObject = new JSONObject();
jsonObject.put("value", "value1");
JSONObject jsonObject1 = new JSONObject();
jsonObject1.put("value2", "value2");
JSONObject jsonObject2 = new JSONObject();
jsonObject2.put("camp1", jsonObject);
jsonObject2.put("camp2",jsonObject1);
//jsonObject2 is the payload to server here you can use JsonObjectRequest
String url="your custom url";
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest
(Request.Method.POST,url, jsonObject2, new com.android.volley.Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
//TODO: Handle your response here
}
catch (Exception e){
e.printStackTrace();
}
System.out.print(response);
}
}, new com.android.volley.Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// TODO: Handle error
error.printStackTrace();
}
});
JsonObjectRequest will accept the payload as json in its constructor after the url parameter we will pass the data

This is tested Code try this:
private void multipartRequestWithVolly() {
String urll = "your_url";
progressDialog.show();
StringRequest request = new StringRequest(Request.Method.POST, urll, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
progressDialog.dismiss();
if (!TextUtils.isEmpty(response)) {
Log.e(TAG, "onResponse: " + response);
textView.setText(response);
} else {
Log.e(TAG, "Response is null");
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
progressDialog.dismiss();
Log.e(TAG, "onErrorResponse: " + error.toString());
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
hashMap = new HashMap<>();
hashMap.put("OPERATIONNAME", "bplan");
hashMap.put("mcode", "298225816992");
hashMap.put("deviceid", "dfb462ac78317846");
hashMap.put("loginip", "192.168.1.101");
hashMap.put("operatorid", "AT");
hashMap.put("circleid", "19");
return hashMap;
}
};
AppController.getInstance().addToRequestQueue(request);
}

try {
RequestQueue requestQueue = Volley.newRequestQueue(this);
String URL = "http://...";
JSONObject jsonBody = new JSONObject();
jsonBody.put("Title", "Android Volley Demo");
jsonBody.put("Author", "BNK");
final String requestBody = jsonBody.toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("VOLLEY", response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("VOLLEY", error.toString());
}
}) {
#Override
public String getBodyContentType() {
return "application/json; charset=utf-8";
}
#Override
public byte[] getBody() throws AuthFailureError {
try {
return requestBody == null ? null : encodeParameters(requestBody , getParamsEncoding());
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", requestBody, "utf-8");
return null;
}
}
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String responseString = "";
if (response != null) {
responseString = String.valueOf(response.statusCode);
// can get more details such as response.headers
}
return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
}
};
requestQueue.add(stringRequest);
} catch (JSONException e) {
e.printStackTrace();
}
Please check with the edited getBody()
#Override
public byte[] getBody() throws AuthFailureError {
try {
return requestBody == null ? null : encodeParameters(requestBody , getParamsEncoding());
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", requestBody, "utf-8");
return null;
}
}

If you calling any REST-API then note that that's payload always be in JSON format. therefor you can use an object body for payload like this way.
HashMap<String, String> params = new HashMap<String, String>();
params.put("username", input_loginId.getText().toString());
params.put("password", input_password.getText().toString());
and you can pass this on method like this way
JsonObjectRequest logInAPIRequest = new JsonObjectRequest(Request.Method.POST, YOUR-URL,
new JSONObject(params), new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
input_errorText.setText(response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
input_errorText.setText("Error: " + error.getMessage());
}
});

Android Volley JsonObjectRequest not send params

I'm trying to send a JsonObjectRequest to my server with some params, but seems like params doesn't arrive at the server. Before to post on SO I try all kind of suggestion found in google but no one works fine..
This is the code of my JsonObjectRequest:
RequestQueue queue = MySingleVolley.getInstance(ctx).
getRequestQueue();
JsonObjectRequest jsObjRequest = new JsonObjectRequest(method,url,null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("REQUEST_JSON_TO_SERVER", "Success: " + response.toString());
}
},new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("REQUEST_JSON_TO_SERVER", "Error: " + error);
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
return headers;
}
#Override
protected Map<String, String> getParams() {
return params;
}
};
MySingleVolley.getInstance(ctx).addToRequestQueue(jsObjRequest);
And these are my param and others:
String url = "url";
//create the hashMap of parameters
database_zappapp db = new database_zappapp(getApplicationContext());
db.open();
HashMap<String, String> params = new HashMap<>();
params.put("action","myAction");
params.put("nomeutente", db.getUsernameLogged());
params.put("token", token);
db.close();
//Send the request to the server
Global.RequestJsonToServer(getApplicationContext(), url, Request.Method.POST, params);
Thanks in advance for the help!
Edit 2
I've changed my params in this creating a string jsonBody:
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("action","gcmUserRegister");
jsonObject.put("nomeutente",db.getUsernameLogged());
jsonObject.put("token",token);
}catch(JSONException e){
e.printStackTrace();
}
String requestBody = jsonObject.toString();
db.close();
and my request like this with getBody():
JsonObjectRequest jsObjRequest = new JsonObjectRequest(method,url,null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("REQUEST_JSON_TO_SERVER", "Success: " + response.toString());
}
},new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("REQUEST_JSON_TO_SERVER", "Error: " + error);
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<>();
headers.put("Content-Type", "application/json");
return headers;
}
#Override
public byte[] getBody() {
try {
return requestBody == null ? null : requestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s",
requestBody, "utf-8");
return null;
}
}
};
But already didn't work! =(
Postman screen:
No user found means that it enter in the if statement and so it works.. with android i receive "result": "null"
The postman screen with app/json:

I've found the solution!
The problem was in the server not in the client, I was getting the data using POST but from the client I was sending a json object so my new php is:
$data = json_decode(file_get_contents('php://input'), true);
//echo "Action: ".$action;
//Registrazione del token
if($data['action'] == "gcmUserRegister"){
......
Thanks al lot to BKS!!!

Change this part of your code:
`JsonObjectRequest jsObjRequest = new JsonObjectRequest(method,url,null ...`
To this:
`JsonObjectRequest jsObjRequest = new JsonObjectRequest(method,url,yourparams..`
Reason: if you are using the default Volley constructors thats the way to send params to Server.
